In a study involving a cell-free translation system from coli, the polyribonucleotide AUGUUUUUUUUUUUU directs the synthesis of the oligopeptide fMet-Phe-Phe-Phe-Phe. In the presence of a new class of translation-targeting antibiotics that bind to the large ribosomal subunit, the ribosomal complex forms, the initiator tRNA binds the mRNA, the second tRNA enters the A site of the ribosome, but no peptide bonds form. Which of the following is a likely function of these new antibiotics?

a. Blocks peptidyl transferase activity
b. Inhibits tRNA aminoacyl synthetase function
c. Inhibits ribosomal translocation along the mRNA
d. Prevents anticodon base-pairing with the codon
e. Blocks binding of the Shine-Dalgarno box to the rRNA

Answers

Answer 1

Answer:

c. Inhibits ribosomal translocation along the mRNA.

Explanation:

Initiator tRNA is thought to bind directly to P-site of small ribosomal sub unit. These tRNA are positioned at P site and remain attached to tRNA located at this site. Initiation factor helps to mediate this event.

Suppose that you close a window because you notice that rain is falling. Your action in closing the window is a(n)

A. involuntary reaction.
B. depressant.
C. stimulus.
D. response.

Answers

Answer:

D. Response

Explanation:

Basically, You Are Coordinating What Is Happening Which Triggers The Brain For A Response.

Answer:

D.

Explanation:

You are responding to the rain by closing the window.

- it is not an involuntary action because that is something that doesn't require thinking such as breathing and blinking.

- it is not a depressant because that is something that reduces functional activity - so affects the body.

- it is not a stimulus because a stimulus is a change or signal in the environment that can make an organism react. So, in this case the rain would be the stimulus.

Consider the following geometric solids.
A sphere with a ratio of surface area to volume equal to 0.3 m
A right circular cylinder with a ratio of surface area to volume equal to
2.1 m?
What results would you expect if these two models were compared in a
diffusion test?
A. The rate of diffusion would be slower for the right cylinder,
B. The rate of diffusion would be the same for the two models.
0
C. The rate of diffusion would be faster for the right cylinder.
D. The rate of diffusion would be faster for the sphere.

Answers

Answer:

the rate if diffusion will be faster in the right cylinder

Explanation:

The surface area to volume ratio of the cylinder is higher. This means that in the cylinder more reactants are exposed at the surface and the rate at which diffusion takes place increases

A genetically heterogeneous population of rice has a mean in the number of days to maturation of 30. Selection for decreased period of maturation is carried out for one generation. The average period to maturation among the plants selected as parents for the next generation is 25 days. F1 plants mature on average in 27 days. Estimate the narrow sense heritability.

Answers

Answer:

h² = 0.6

Explanation:

Before answering the question, we need to know a few concepts.

Artificial selection is the selecting practice of a specific group of organisms in a population -that carry the traits of interest- to be the parents of the following generations.

Parental individuals carrying phenotypic values of interest are selected from the whole population. These parents interbreed, and a new generation is produced.

The selection differential, SD, is the difference between the mean value of the trait in the population (X₀) and the mean value of the parents, (Xs). So,  

SD = X₀ - Xs

Heritability in the strict sense, h², is the genetic component measure to which additive genetic variance contributes. The heritability might be used to determine how the population will respond to the selection done, R.  

h² = R/SD

The response to selection (R) refers to the metric value gained from the cross between the selected parents. R can be calculated by multiplying the heritability h², with the selection differential, SD.  

R = h²SD  

R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),  

R = X₀ - X₁

-------------------------------------------------------------------------------------------------------------

Now that we know these concepts and how to calculate them, we can solve the proposed problem.

Available data:  

You are selecting rice´s decreased period of maturation. The population of rice has a mean maturation time of 30 days → X₀ Parental selected average period to maturation is 25 days → Xs F1 plants mature on average in 27 days → X₁ N arrow sense Heritability → h²

According to what we sow previously, we need to find out the value of h².

We know that h² = R/SD, so we need to get R and SD first.  

R = X₁ - X₀

R = 27 - 30

R = -3

SD = Xs -  X₀  

SD = 25 - 30

SD = -5

Knowing this, we can calculate h²

h² = R/SD

h² = -3/-5  

h² = 0.6

As part of a resource recovery project, a city decides to open reuse centers.
What kind of materials might a reuse center accept?
A. Household garbage
B. Industrial waste
C. Leftover art supplies
D. Yard trimmings

Answers

The reuse center might accept: D. Yard trimmings

What is a reuse center?

A reuse center, also known as a recycling center or a second-hand store, is a facility where various materials and items that are still in usable condition are collected, sorted, and made available for resale or redistribution. The main goal of a reuse center is to divert materials from the waste stream and promote their reuse, extending their lifespan and reducing the demand for new products.

These centers typically accept a wide range of items, such as furniture, appliances, clothing, electronics, books, toys, and more. By accepting and selling these items at affordable prices, reuse centers help reduce waste, conserve resources, and provide affordable options for individuals and communities.

A reuse center can accept yard trimmings as it include grass clippings, leaves, branches, and other organic waste from landscaping and gardening activities.

plz give a correct answer for the question how do canine and molar differ​

Answers

Answer:

Canines are the sharp, pointed teeth that sit next to the incisors and look like fangs. Dentists also call them cuspids or eyeteeth. Canines are the longest of all the teeth, and people use them to tear food

Molars are the flat teeth at the rear of the mouth. Each molar typically has four or five cusps. They are used exclusively for crushing and grinding. Wisdom teeth are also called third molars. They erupt from the age of 18 onwards but are often surgically removed.Their function is similar to that of the premolars, to grind, tear, and crush food. Molars have a large flat biting surface which makes them perfect for this job.

Explanation:

Hope it works!!!!

A student is conducting their science experiment on the effect of caffeine on dogs. He has 3 groups of test subjects. The 1st group of dogs receives plain water. The 2nd group of dogs receives 10 mg of caffeine each, and the 3rd group receives 50 mg of caffeine each. He will measure their activity levels by recording how long each dog runs without stopping, after giving them the pills. What is the dependent variable in this experiment?

Answers

Answer:

The amount of activity  

Explanation:

In an experiment, the independent variable is the variable that the scientist/investigator purposely changes or manipulates, which isn't changed by other variables in the experiment (in this case, the amount of caffeine). On the other hand, the dependent variable is the variable that is being measured or tested during the experimental procedure (this variable is 'dependent' on the independent variable). Finally, the control group is defined as the group of individuals/subjects who do not receive the experimental treatment (in this case, the dogs that receive water).

Answer: The amount of activity.

Send a detailed email is the best way to deliver an update to her because in the email he can send all the information in detail form which can satisfy his owner. He can't call or message because it takes too much time to provide information so email is the best way to provide information.
